Description

Technical Field

[0001] This utility model belongs to the field of farmland irrigation technology, and in particular relates to a water flow power generation device that provides power to electric valves. Background Technology

[0002] In water pipelines, valves are essential components. To achieve automatic valve control, electric valves are often used to open and close them. These electric valves require a power source; however, in certain environments, there is no power supply, or installing power lines is cumbersome or costly. For example, in farmland irrigation systems, the main pipeline connects to multiple branch pipelines via distributors, which are typically located in the fields. To achieve precision irrigation and remote control, the distributors use electric valves to control the flow of branch pipelines. However, laying power lines in the fields presents problems such as high cost and maintenance difficulties. Existing technologies use solar energy or batteries for some devices, but these suffer from drawbacks such as susceptibility to weather conditions and insufficient power endurance. Therefore, there is an urgent need for an efficient and stable power supply solution.

[0003] Currently, there are devices that generate electricity using water flow, but they are mostly suitable for larger pipe diameters or high flow velocity scenarios, and their structures are complex and inconvenient to install. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a water flow power generation device that provides power to electric valves. It has a simple structure, is easy to install, and solves the problem of power supply for electric valves.

[0005] The purpose of this utility model is achieved as follows: a water flow power generation device that provides power to an electric valve includes a rotor driven to rotate by water flow inside a water pipe, with several magnetic blocks distributed in a ring around the rotor; and one or more coil assemblies fixedly arranged outside the water pipe at the positions corresponding to the magnetic blocks.

[0006] Preferably, the rotor includes a rotor bushing and a rotor ring arranged concentrically, with multiple blades arranged in a ring between the rotor bushing and the rotor ring, and several magnetic blocks arranged in a ring embedded on the rotor ring.

[0007] Preferably, a bracket is fixedly installed on the inner wall of the water pipe. The bracket includes a bracket bushing and a bracket ring. Multiple annular distributed radial plates are connected between the bracket bushing and the bracket ring. The rotor is rotatably mounted on the bracket through a central shaft installed between the bracket bushing and the rotor bushing.

[0008] Preferably, the coil assembly includes a coil holder disposed on the wall of the water pipe, a coil housing fixedly mounted on the coil holder by screws, and a coil winding disposed inside the coil housing.

[0009] Preferably, the coil housing includes a housing and a cover.

[0010] Preferably, the magnetic blocks are made of neodymium iron boron material, the number of magnetic blocks is even, and the magnetic blocks are arranged with alternating N and S poles.

[0011] Preferably, it also includes a rectifier module and a battery. The coil assembly is connected to the rectifier module via wires, and the output of the rectifier module is connected to the battery to convert the AC power output by the coil assembly into DC power and store it in the battery for powering the electric valve.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] (1) Structural optimization: The external coil avoids the risk of water immersion and leakage, while the internal rotor does not affect the original pipeline structure and is easy to install.

[0014] (2) Energy self-sufficiency: The irrigation water flow generates electricity, eliminating the need to lay power lines and reducing the cost of field engineering.

[0015] (3) High efficiency and stability: The neodymium iron boron magnet and alternating magnetic pole design improve power generation efficiency and are suitable for low flow rate (such as farmland irrigation) and small pipe diameter scenarios.

[0016] (4) Reliable range: The battery energy storage solution overcomes the shortcomings of solar energy being affected by weather, ensuring the continuous operation of electric valves.

[0017] (5) Easy maintenance: The modular design supports quick disassembly and repair, reducing system downtime.

[0018] (6) Strong adaptability: By adjusting the number of magnetic blocks, the number of coil turns and the blade angle, it can be flexibly adapted to different flow requirements and has a wide range of applications.

[0019] (7) Green and environmentally friendly: No carbon emissions, in line with the trend of sustainable agricultural development, and reduces long-term operation and maintenance costs.

[0020] (8) Application scenarios: It is especially suitable for remote control power supply of electric valves of water distributors in farmland irrigation systems, and can also be extended to industrial pipelines, urban water supply systems and other scenarios. When linked with intelligent control systems, it can realize functions such as flow monitoring and valve opening adjustment, forming a complete smart water solution. Attached Figure Description
